Waterworld suffered from hype and high expectations, particularly when it was basically a remake of Road Warrior, but with ocean instead of desert, soil instead of oil, and smokers on jet skis led by The Deacon instead of marauders on motorcycles led by The Humungus. There was even a goofy inventor with a flying machine, a cute but retarded kid, and a love interest who ends up ultimately disappointed when the savior leads them to salvation and then abandons them to return to his lonely life of drifting.That said, Road Warrior was a great movie, and so was Waterworld... but the budget for the former was $4.5m, while the budget for the latter was $175m, so without really adding something special, it was going to be overrated.

I never understood the drinking your own pee thing. I mean if you can make a machine that can filter urine into drinking water, why can't you make a machine that can filter sea water into drinking water?

I don't know if Waterworld is the best movie ever about Kevin Costner drinking his own pee.I mean it's pretty good movie about him drinking his own pee, but not his best when you consider some of his other ones.
